3e it known that l. WILLIAM H. J. Frrz- GERALD, a citizen of the llnitedStates. re-

J siding at Braintree. in the county of Nor- 7 the construction ofdeniountable wheels relativcto the means for attaching the wheels toadapted to receive the rectangular portions otthe stud members 10, 10.The demountable wheel includes the spokes 1Q, 12 and the collar 13 withits flange ll so that when the nuts 11, 11 are removed from the studmemi (3 has a series of transverse perforations in folk and State ofMassachusetts. have invented certain new and useful Improvements inDemountable Vheels. of which the 1 following is a specification.reterencebeing i had to the accompanyingdrawings. forming part thereof.f

This invention has reference to improvements in wheels demountablyattached to hubs whereby the wheels'with the tires.

thereon may be removed and demount-ed from the hubs and replaced byother similar 5- collar 13 of the clamping plate 14. which wheels havinginflated tires.

The ob ect of the invention is to nnprove the hubs. v

Other objects of the invention will appear from the followingdescription. The invention consists in the demountable wheel hereinafterdescribedand claimed.

Figure 1. represents a cross sectional view i of a demountable wheeltaken on line 1- Fig. 2. illustrating my invention. Fig. 2, represents aface view of the clamping and l l l l sustaining member'tor the wheelspokes. also showing portions of said spokes in position. part of saidclamping plate being broken away to show the manner in which the studsare engaged With the spokes.

Similar characters of reference designate corresponding partsthroughout. I

In carrying this invention into practice 'I take the hub 5 having theflange 6 rotatably mounted on th axle or spindle S and adapted to besecured in any ordinary manner to rotate on said axle or spindle S. Theflange 5 which are secured the contracted stud members 7. 7 having theenlarged ]')ort ions. 8. 8 mailing shoulders bea ring againstthe flangeG. The stud members 7; 7 are secured in the perforations of the flange 6by means of the nuts 9,0 or in any other suitable manner so that saidstuds are fixedly secured in position. The outer ends of the studenlargements 8. 8 have the contracted portions 1O. 1O rectangular inshape for a portion of their length and having screw threaded. endsadapted to receive the nuts 11, 11

The meeting faces of the spokes 12, 12 have perforations 13. 13 adaptedto be freely received on the enlargements 8, 8 of the studs. and it isnoticed in Fig. 1 that the spokes 12. 12, have a thickness slightlyexceeding the length of said stud enlargements S. 8 so that when thespokes are engaged with such enlargements. the outer faces of the spokesextend in planes slightly offset from the outer ends of saidenlargements 8, 8- Y The inner ends of the spokes 12. 1.2.9.1'6received" and frictionally engaged by the.

plate is adapted to be received by the hub 5 and has a series ofrectangular perforations removed and replaced by a similar wheel havingthe perforations 13. 13 adaptml to be received by the stud enlargements5%. S.

lVhen such wheel is in place the nuts ll, 11

are screwed onto the several stud members.

10, 10 and the clamping plate 14-. is brought -to bear against the outerfaces of all the spckes. thus to some extent exerting a pressure on allof the spokes. this being permitted by the fact that the enlargements 8,8 of the stud members and the collar 13' are shorter than the diameterof the spokes.

x By the use of the rectangular portions of the stud members l0. 10 thenuts 11, 1.1 may be screwed tightly into position without tendency ofetlectu ig the rotation of the studs and the loosening ot the same inany 'way troni the nut-s 9. 9.

I Having thus described my invention I claim as new and desire. tosecure by Letters Patent.
